The scent of the hair and scalp booster is very nice and mild. even though rosemary is somewhere near the bottom of the list, that's what I smell the most. Oh BTW I just washed my hair and decided to use a little of the detangler oil. As far as detangling, my hair was already that, so I can't speak on it's detangling effects, but I am totally IN LOVE with the smell. I'll probably keep buying it just for that. Oh and it's very, very light. It doesn't have a greasy feel at all. I like it. /images/graemlins/smile.gif
